What are Polarized Lenses?

Polarized lenses are known for their ability to block the glare that reflects off of certain surfaces. This makes them very popular among people who spend a lot of time outdoors, on the road and around bodies of water.
But polarized lenses aren’t just for people who love boating, fishing or lounging on the beach. Anyone who is bothered by outdoor glare can benefit from this type of sunglass lens.
Polarized lenses can be helpful for driving too, since they reduce the glare that reflects off of cars and light-colored pavement.
Some light-sensitive people, including those who have recently had cataract surgery, can also benefit from polarized lenses.

What does “polarized” mean?

When a lens is polarized, it has a built-in filter that blocks bright, reflected light. This intense light is known as glare.
When glare is reduced, your eyes feel more comfortable and you can see your surroundings more clearly.
Sunlight scatters in all directions. But when it strikes flat surfaces, the reflected light tends to become polarized, meaning the reflected rays travel in a more uniform (usually horizontal) direction.
This creates an annoying, sometimes dangerous intensity of light that can reduce visibility.
